   <span class="function"><strong>pg_set_error_verbosity()</strong></span> sets the verbosity mode, returning the connection&#039;s previous 
   setting. In <strong><code>PGSQL_ERRORS_TERSE</code></strong> mode, returned messages include severity, primary text, and 
   position only; this will normally fit on a single line. The default mode (<strong><code>PGSQL_ERRORS_DEFAULT</code></strong>)
   produces messages that include the above plus any detail, hint, or context 
   fields (these may span multiple lines). The <strong><code>PGSQL_ERRORS_VERBOSE</code></strong> mode includes all available 
   fields. Changing the verbosity does not affect the messages available from 
   already-existing result objects, only subsequently-created ones.
